Product Description:

The MDD021B-N-100-N2K-032MA0 is a brushless synchronous motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for use with compatible digital drive controllers, the unit converts electrical command signals into mechanical rotation for small pick-and-place heads, indexing tables, or feeder mechanisms in industrial automation. Its compact frame minimizes moving mass while maintaining the thermal capacity needed for continuous cyclic duty in tightly integrated machinery. The brushless motor layout also supports accurate speed and position control in small axes that require repeatable motion.

A centering pilot of 32 mm helps align the motor on the mounting face and supports predictable runout after installation. All terminations are routed on Side A, and a keyed Connector carries both power and signal conductors through one connection point. Under locked-rotor conditions, the stator can sustain 0.30 Nm of continuous torque, which provides holding force for micro-increment moves at low current. Rotor position is reported by an Integrated absolute encoder, so the drive has an immediate position reference at startup. Because the motor is delivered without a blocking brake, static holding during power loss must be provided by external clamping or drive torque.

During dynamic operation, the drive receives real-time rotor information through the embedded resolver feedback, enabling smooth vector control up to a rated speed of 10000 rpm. The single-ended shaft is machined with a keyway, which simplifies torque transmission to miniature couplings while preserving alignment accuracy. The rated speed allows quick movement in compact axes where short cycle times are important. The keyed shaft also provides positive torque transfer to small couplings and driven elements.
